A Three-Dimensional Kinematic and Kinetic Study of the College-Level Female Softball Swing
Softball Sport Biomechanics Softball Bat Softball Swing Kinematics Kinetics
2015/5/21
This paper quantifies and discusses the three-dimensional kinematic and kinetic characteristics of the female softball swing as performed by fourteen female collegiate amateur subjects. The analyses w...
A gender-based kinematic and kinetic analysis of the snatch lift in elite weightlifters in 69-kg category
Biomechanics weightlifting body weight category
2015/5/8
The objective of this study was to compare the kinematic and
kinetic differences in snatch performances of elite 69-kg men
and women weightlifters, the only category common to both
genders. The ...
Kinetic Assessment of Golf Shoe Outer Sole Design Features
Club driver grass ground- reaction-force insole-pressure spikes
2015/4/24
This study assessed human kinetics in relation to golf shoe outer sole design features during the golf swing using a driver club by measuring both within the shoe, and beneath the shoe at the natural ...
Kinematic Analyses of the Golf Swing Hub Path and its Role in Golfer/Club Kinetic Transfers
Golf biomechanics golf swing kinematics golf swing kinetics
2015/4/22
This study analyzed the fundamental geometric and kinematic characteristics of the swing hub path of the golf shot for four diverse subjects. In addition, the role of the hub path geometry in transfer...
The Effects of Kinetic Energy on Concentric and Eccentric Isokinetic Work
Kinetic energy kinetic error work measurement type
2015/4/7
This investigation examined inertial effects on work output during isokinetic concentric knee extension and eccentric knee flexion. Total work (Wtotal) included work due to kinetic energy (Wkin), with...
Jump Kinetic Determinants of Sprint Acceleration Performance from Starting Blocks in Male Sprinters
Anthropometry horizontal jumps sprint performance vertical jumps
2015/3/18
The purpose of this research was to identify the jump kinetic determinants of sprint acceleration performance from a block start. Ten male (mean ± SD: age 20 ± 3 years; height 1.82 ± 0.06 m; weight 76...
KINETIC CONSEQUENCES OF CONSTRAINING RUNNING BEHAVIOR
Ground reaction force, impact attenuation, shock
2015/3/17
It is known that impact forces increase with running velocity as well as when stride length increases.
Since stride length naturally changes with changes in submaximal running velocity, it was not c...
Kinetic Constrained Optimization of the Golf Swing Hub Path
Golf swing biomechanics hand path optimization kinetics kinematics
2015/5/25
This study details an optimization of the golf swing, where the hand path and club angular trajectories are manipulated. The optimization goal was to maximize club head velocity at impact within the i...
